SALINA, Kansas (AP) – A Salina middle school student has been arrested after authorities say he stabbed another boy with an awl during a class.

Lt. Scott Siemsen of the Salina Police Department says the 13-year-old boy is accused of causing a puncture wound when he stabbed the other boy’s shoulder with the awl during a technology class at South Middle School. The boy’s wound was bandaged by the school nurse. An awl is a pointed spike that can be used for such things as poking holes into leather.

Siemsen says the incident was not preceded by any argument or confrontation between the boys.

Siemsen says the boy accused of stabbing the other student is being held at the Saline County Juvenile Detention Center.
